Highlights

China National Space Administration has launched its two satellites that detects the gravitational waves into the planned orbit on 9th December 2020.

Points To Note

  • The chinese satellites were launched from the Xichang Satellite Launch Center in Sichuan province.
  • These satellites are part of the GECAM (Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor) mission.
  • The satellites were launched from a Chang Zheng 11 or Long March-11 carrier rocket.
  • It was the 355th mission of the Long March rocket series.
  • China’s GECAM project is being carried by the Chinese Academy of Sciences (CAS).
  • The Chang Zheng 11 rocket has been developed by the China Aerospace Science and Technology Corporation (CASTC).

Uses of satellites

These two Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor satellites will be used

  1. To Monitor the high-energy celestial phenomena including the gravitational wave gamma-ray bursts, special gamma-ray bursts, magnetar bursts and high-energy radiation of fast radio bursts.
  2. To Study neutron stars, black holes, other compact objects and the merger processes of these objects.
  3. To Detect the high-energy radiation phenomena in space including the solar flares, Earth gamma flashes and Earth electron beams.
  4. The satellites will also provide observation data for scientists.

GECAM

Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor is a project of the focus laboratory for astroparticle physics. It has been started by the Institute for High Energy Physics and the National Center for Space Science (NCSS) of the Chinese Academy of Science. The GECAM project will investigate the sources of gravitational waves with the help of two small satellites. Each of the satellite weights 163 kilogram. It will orbit around the earth at opposite points in an identical orbit. China launches Satellites for Gravitational Wave Detection China launches Satellites for Gravitational Wave Detection
